To /zZZ whom t may conf/ewa.'

lie it known that l, JOHN Euro1-Lin, a citizen of Ukraine, residing atlf'iyde Park, in the county of Suffolk and State of Massachusetts, haveinvented certain new and useful improvements in Spring Heels, of whichthe following is a specification.

l` his invention relates to certain new and useful improvements inspringl heels for hoots or shoes wherein a plurality of metallic springsare interposed between the upper and lower lifts of a heel withtelescopic sections constituting a part of the heel enclosing1 thespring. a n

lhe primary obgect of theV invention resides in the provision of aspring heel of the type above set forth, and particularly wherein coilsprings are employed, the particular manner of anchoring the ends of thecoil springs to the upper and lower lifts of the heel embodying platesto which the ends of the springs are seciired while the plates arerespectively secured to the upper and lower lifts.

lVith the above and other objects in view the invention consists of thenovel form, combination and arrangement of parts hereinafter more fullydescribed, shown in the accompanying drawing and claimed.

ln the drawing, wherein like reference characters designatecorresponding parts throughout the several views,

Figure 1 is a longitudinal sectional view of a spring heel constructedin accordance with the present invention, showing metallic coil springspositioned between upper and lower lifts of a heel with telescoping sidewalls of the heel inclosing the springs, and further showing the springsanchored at their upper and lower ends to the lifts of the shoe heel,

Figure 2 is side elevational view of the upper and lower lifts removedfrom the heel with the coil springs interposed therehetween and anchoredto said lift,

Figure 3 is a fragmentary tcp plan View of the construction shown inFig. 2 with the upper lift removed to show the anchorplate for the endsof the coil springs,

Figure 4 shows perspective views of the spring anchoring plates andfastening staples associated therewith,

Figure 5 is a longitudinal sectional view of a modified form of springheel showing the use of return bent band springs,

Figure 6 is a horizontal sectional view of the heelshown in Fig. 5villustrating the 1ongitudinally extending leaf springs in top plan view,and y Figure 7 is a top plan view oftherheel shown in Fig. 5 removedfrom ,the upper and illustrating the staple fastening for securing Vtheheel to the upper.

-Referring more in detail to the accompanying drawing, and particularlyto Figs. 1 to 4, there isJ illustrated a spring .heel for boots or shoesassociated with the upper 1 and embodying upper and lower sections 2 and3 respectively.

The upper section 2 embodies a lift 4 having marginally secured theretoa depending skirt or apron 5 formed of any suitable Inay ,y

terial, such as metal, leather or rubber.

The lower heel section 3 embodies a lift (3 carrying a marginalupstanding skirt orv flange 7 vthat telescopes within the ange 5depending from'the upper heel section 2 as d shown in Fig. 1, while atread block 8 of i rubber is secured to the lower face of the i lift 6.

As shown more clearly in 1 and 2, a

plurality of metallic coil springs 9 are iny tei-posed between the upperand lower lifts 4 and 6, the opposite ends of the coil springs 9 beinganchord to plates thatare in turn respectively securedv to the adjacentlifts. The anchoring plates 10 associated with each end of the spring isshown more clearly in Fig. 4, the same being of substantiallyrectangular formation in plan view having a tapering or wedge shapedslot 11 formed in one end thereof while the opposite end is apertured asat 12. The formation of the wedge shaped block 11 provides side legs 13in the anchoring plate 10, the outer ends of which are apertured as at14 for purposes presently to appear. The end 9a of the coil spring 9 isforced into the wedge slot 11 in the anchoring plate 10 with theterminal Y end of said spring directed through the opening 12 as shownmore clearly in Figs. 2 and 3. A U-shaped staple 15 has the side thereofpassed therethrough the openings 14 in the vlegs 13 of the anchoringplate and are associated with the lifts 4 of the upper section of theheel and the shoe upper 1 in a manner to constitute a fastening devicefor the heel. The anchoring plate 10 is associatedwith the lower' endsof the spring 9 and are secured to the lower lift 6 by fastening devices16 as shown in Fig. 2, thereby forming a connection between the upperand lower sections 2 and 3 of the heel. y

From the above detail description of the device, it is believed thatthek construction and operation thereof will at once be apparent, itbeing noted that the coil springs 9 are confined within theV marginalflanges 5 and 7 carried by the upper and lower sections of the heel andtelescoping within each other, the anchoring plates l() constitut-v inga positive anchoring means for the ends of the springs and an easymethod of securing the same to the lifts of the upper and lowersections.

In the form of the invention shown in Figs. 5 and 7, the upper lift laof the heel is provided with a marginal depending skirt or flange 5Lthat incloses the lower lift 6u that carries a rubber tread block 8a. Inlieu of the coil springs Qreturn bent leaf springs 17 are employed, thesame being arranged side byside and extending longitudinally of the heelas illustrated in Fig. 6, the lower ends of the` vleaf springs 17 beingsecured as at 16a to the lower lift 6, while similar fastening devices16 secure the upper ends of said springs to the upper lift 4a. Theconnection between the upper lift laf and the shoe, upper l embodieslli-shaped staples 15@L extending through the upperlift 4a. and the shoeupper la as shown inFiigs. 5 and 7.

lVhile there are herein shown and described the preferred embodiments ofthe invention, it is neverthelessto be understood that minor changes maybe made therein without departing from the spirit and; scope thereof asclaimed.

Vhat is claimed as new is l. In a spring heel for shoes, upper andvlower telescoping sections, coil spring interwedge-shaped slot thereinfor receiving the end of the spring, and lmeans for securing theanchoring plates to the adjacent sections.

2. In a spring heel for shoes, upperrand lower telescoping sections,coil spring interposed between the sections, anchoring plates associatedwith the ends of the springs, and each being of rectangular formationhaving a wedge-shaped slot therein for receivinglthe end of the spring,means for securing the lower anchoring plates to the lower section, andU-shaped staples securing the upper anchoring plates to the uppersection and shoe upper.

3. In a spring heel for shoes, upper and lower telescoping sec-tions,coil springs interposed between the sections, anchoring platesassociated with the ends of the springs, and each being of retangularfor'- mation having a wedge-shaped slot therein for receiving the enelof the spring, said slot forming side legs having openings in theI endsthereof, means for vsecuring the lower anchoring plates to the lowersection, and U-shaped staples inserted in the Yleg openingsof the upperanchoring plates for securing the upper ends of the springs to theupperI heel section and shoe upper.

In testimony whereof I afiiX my signature.

JOHN DUTCHAK.
